(cies-38) `l` Claims.

This 4invention relates to the art of heating and Ventilating, and moreparticularly the invention has reference to a casing to be used inassociation with a gas heater, or any other suitable type of heater, tothe end that the heatedair will be distributed to advantage in a room orother enclosure for raising the temperature thereof.

In accordance with the present invention, there is provided a casingthat may be readily disposed over a gas heater or the like, and soconstructed and equipped as to direct the heated air downwardly close tothe floor of the room to the end that the temperature in the room willbe raised in the region of the floor level, and lowered in the region ofthe ceiling to the greater comfort of the occupants of such room orother compartment.

The invention, together with its objects and advantages, will be bestunderstood from a study of the lfollowing description taken inconnection with the accompanying drawings wherein- Figure 1 is a frontelevational view of a casing embodying the features ofthe presentinvention.

Figure 2 is a side elevational view thereof` Figure 3 is a rearelevational view of the casing.

Figure 4 is a Vertical sectional view through the casing.

Figure 5 is a vertical sectional view through the casing taken at rightangles to Figure 4.

Figure 6 is a horizontal sectional view through the upper portion of thecasing, and

Figure 7 is a detail sectional view hereinafter more fully referred to.

Referring more in detail to the drawings, Ait will be seen that thecasing, indicated generally by the reference numeral 5, is formed frommetal or other suitable material, and, generally speaking, of anysuitable shape and design.

However, a salient feature of the present in'- vention resides in havingthe casing provided with a topV wall 6 that slopes forwardly and alsolaterally as at lia-6a towards opposite sides of the casing.

At the front edge thereof, the top wall 6 deiines the upper edge of ahot-air discharge opening 8 provided in the upper portion of the frontwall 1 of the casing.

The opening 8 extends substantially from one side to the opposite sideof the casing, and opposite end portions of the opening incline or slopetowards the opposite sides of the casing, as shown, to followsubstantially the inclines 6a of the top wall 6. 1 l

Further in accordance withthe present invention, `the casing 5 isdivided internally, and 55V 24 through the medium ofy a partitionf'intoa relatively deepv lower heater-accommodating compartment IU toaccommodate a gas heater or the like,.'andan lipprrelatively shallowYhot-air Ydistributing compartment II for which the opening 8 provides anoutlet;4 e

The partition 9 has oppositely inclined side sections 9a,9a, and anintegral rearwardly in clined section 9b, with the edges of the sections9a, `9a and 9b at the point of Agreatest height in the partitionVdefining with the .front wall 'Ia through opening 24 through which theheat from the compartment II) passes upwardly into the compartment I Ifor heating a forced circulation of air within the compartment` I I assuch air discharges `through the opening 8 from the com-y partmen't.v 'v

Also, the side sections 9d of the` partition 9 are provided with lcuvers25 through which heat or products of combustion from the chamber IIIalso vpass into the chamber Yor compartment I I for heatingthe airas itis forced therethrough.

`To 4provide for a forced circulation', of air through the compartment II and into the room in which the casing is positioned, there is mounted,exteriorly of the casing 5, and in alignment with a .cold-air opening I3provided in the rear wall I2 of the casing, a power-driven fan I4.

A suitable mounting bracket I5 is provided,` as shown, for the fanI4.

It will thus be seen that the fan I4, when in op-` eration, will drawair into the compartment II from the atmosphere through the inlet I2 andforce air thus drawn in from the compartment I I through the air outlet8.

The inclination or slope of the top wall 5 will` 'the proper temperaturein a room are obtained. Also, the shape of the partition 9 is such thatmaximum heating surface is formed thereby to be contacted with by theair within the compartment II for quickly raising the temperature ofsuch air as it travels through the compartment and discharges into theroom.

Further to insure such intimate contact of the air with the heatingsurfaces provided 4by the partition 9, there is suitably mounted on thepartition to rise vertically therefrom within the com'. partment I I, abaille 26.

The baffle `26 is disposed adjacent the opening and in substantiallyalignment withfthe cold-` air inlet I3 so that the air entering thecompartment Il will strike the baille and be forced towards oppositesides of the compartment ll and Iconsequently to contact with all of theavailable heating surface provided by the partition 9.

Access to the heater (not shown) as accommodated within the compartmentI of the casing for igniting such heater, or other purpose, may be hadthrough the medium of a pivotally mounted door 2| provided on the frontwall 1 of the casing as shown.

It is believed that the advantages of a easing of this character, whenused with a gas burner or the like, will be clear to and appreciated bythose familiar with the art of heating and ventilatins.

It is also to be understood that we do not limit ourselves to theprecise embodiment of the invention as herein illustrated, since changesmay be made by those skilled in the art.

Having thus described the invention what, is claimed as new is:

1. A casing adapted to be used in conjunction With a heater, said casingbeing divided by a partition into a'relatively deep lower compartmentfor accommodating a heater, and a relatively shallow upper hot-airdistribution compartment, said casing having in the front wall thereofan opening elongated transversely of the casing in the region of saidhot-air distribution com partment and serving as a hot-air outlet forsaid compartment; said casing also having in the rear wall thereof andin the region of said hot-air distribution compartment a cold-air inletopening, and a power-driven fan mounted exteriorly I in oppositedirections towards opposite sides of the casing, and said hot-airvdischarge opening having Oppositely inclined end portions continuingsubstantially` to the'side Walls of said casing.
